Ok I'm getting a bit lost with this wiring for the alternator to the battery and the fuseable link they got on the old wiring and the ones they are giving me dont have it

Ok so heres the old wire that im replacing


The plug plugs into this


The red wire from the plug runs to this


and the orange wire from the plug runs to this


And ive went and talked to every autostore in town even GM and they cant find a wire like it

This is the one they say is replacement


I just dont see how to connect these together to make one like that old one or does anyone know how to wire this up correctly cause this is one big headache at this point

any help is appreciated
